Referring to FIG. 1 to FIG. 4 , in accordance to an embodiment of the present invention, a smart interactive toy is provided, which includes a shell 100, an interactive control module 200, and a moving mechanism 300. The interactive control module 200 is installed in the shell 100, the moving mechanism 300 is installed in the shell 100 and used for driving the shell 100 to move. The moving mechanism 300 is also connected electrically with the interactive control module 200.

The smart interactive toy also includes an anti-fall sensing module 400 comprising a first signal sending unit 410 and a signal receiving unit 420.

The first signal sending unit 410 is mounted on the shell 100 and has a direction of signal transmission towards the horizontal plane at a specific angle. The first signal sending unit 410 is connected electrically with the interactive control module 200 and sends a first sensing signal in the direction of signal transmission.

The signal receiving unit 420 is mounted on the shell 100, connected electrically with the interactive control module 200 and used for transmitting a first electrical signal to the interactive control module 200 when a first reflected signal, reflected after the first sensing signal meets an obstacle, is not received by the signal receiving unit 420 in a predetermined time period, so that the interactive control module 200 drives the moving mechanism 300 to stop moving, turn and retreat.

When the smart interactive toy provided in the present invention is used, after the interactive control module 200 receives external control instructions from the users, it controls the moving mechanism 300 to drive the shell 100 to move. In the moving process of the shell 100, the first signal sending unit 410 transmits the first sensing signal in the direction of signal transmission. When the signal receiving unit 420 does not receive the first reflected signal, reflected after the first sensing signal meets an an obstacle, in a predetermined time period, it indicates that the smart interactive toy is at an edge of a table top or encounters a deep pit, and it will fall down if it continues to moving forward. At this time, a first electrical signal is sent to the interactive control module 200 by the first signal sending unit 410 so that the interactive control module 200 drives the moving mechanism 300 to stop moving, turn, or retreat, thereby achieving that the user controls the smart interactive toy to avoid it from falling down the table or into the deep pit, which ensures that the smart interactive toy can be interacted and is not easy to damage.

In accordance to the other embodiment of the present invention, the range of the specific angle is 0°˜90°. It should be understood that when the direction of the signal transmission of the first signal sending unit 410 faces towards the horizontal plane and is set at a specific angle with the horizontal plane, the first signal sending unit 410 is mounted on the shell 100 and the front end of the first signal sending unit 410 faces to a ground of a traveling direction of the shell 100. With these structures, it is greatly convenient for performing anti-fall detection during the travel of the shell 100.

Further, in accordance to another embodiment of the present invention, the first signal sending unit 410 is an infrared emitter, the signal receiving unit 420 is an infrared receiver. The first sensing signal is a red light emitting by the infrared emitter. In a predetermined time period, if the signal receiving unit 420 receives the first reflected signal, reflected after the first sensing signal meets the obstacle, it indicates that there is the obstacle ahead, the smart interactive toy needs to avoid the obstacle. In a predetermined time period, if the signal receiving unit 420 does not receive the first reflected signal, reflected after the first sensing signal meets the obstacle, it indicates that the smart interactive toy is at an edge of the table top, and it needs to stop moving. A first electrical signal is sent to the interactive control module 200 by the first signal sending unit 410 so that the interactive control module 200 drives the moving mechanism 300 to stop moving, turn, or retreat, thereby avoiding the smart interactive toy from falling down.

To achieve a more accurate or multi-angle anti-fall detection, a plurality of the first signal sending units 410 may be provided on the periphery of the shell 100, and the directions of the signal transmission of each of the first signal sending units 410 faces to the horizontal plane at a specific angle so as to realize multi-angle and multi-point detection. The detection can be performed alternatively by a plurality of the first signal sending units 410. That is to say, the interactive control module 200 successively determines whether the signal, transmitted by each of the first signal sending unit 410, is reflected through each of the signal receiving units 420, thereby realizing the anti-fall detection with a plurality of the first signal sending units 410.

Referring to FIG. 3 and FIG. 4 , in accordance to another embodiment of the present invention, the shell 100 is provided with a power supply module 500 used for charging the interactive control module 200, the moving mechanism 300 and the anti-fall sensing module 400. The power supply module 500 can be a rechargeable or non-rechargeable battery as required.

Referring to FIG. 3 and FIG. 4 , in accordance to another embodiment of the present invention, the anti-fall sensing module 400 also comprises at least a second signal sending unit 430 mounted on the shell 100. The second signal sending unit 430 is also connected electrically with the interactive control module 200 and used for transmitting a second sensing signal. When the signal receiving unit 420 receives a second reflected signal, reflected after the second sensing signal meets an obstacle, in a predetermined time period, a second electrical signal is sent to the interactive control module 200 so that the interactive control module 200 drives the moving mechanism 300 to stop moving or avoid the obstacle. When the signal receiving unit 420 receives the second reflected signal, reflected after the second sensing signal meets the obstacle, in a predetermined time period, it indicates that the travel direction of the shell 100 has the obstacle, therefor it needs to avoid the obstacle or stop moving. The second electrical signal is sent to the interactive control module 200 so that the interactive control module 200 drives the moving mechanism 300 to stop moving or avoid the obstacle.

Specifically, the second signal sending unit 430 may be arranged at an angle flush with the horizontal lane, so that a direction of signal transmission of the second signal sending unit 430 is flushing with the horizontal plane, or slightly above, or slightly below the horizontal plane.

Specifically, the number of the second signal sending unit 430 may be arranged as desired, such as two. Referring to FIG. 1 and FIG. 3 , when the number of the second signal sending unit 430 is one, two of the second signal sending unit 430 are provided on both sides of the first signal sending unit 410 to realize linear arrangement, obstacle avoidance and anti-fall detection in the travel process. Similarly, when one of the first signal sending units 410 and two of the second signal sending units 430 work together, the detection may also be performed alternatively.

In accordance to another embodiment of the present invention, when there are multiple of the second signal sending units 430 and multiple of the first signal sending units 410, and both of the first signal sending units 410 and the second signal sending units 430 are infrared emitters, combined with a signal receiver with the infrared receiver, the anti-fall detection and the avoiding obstacle detection are realized on the basis of multiple of the infrared emitters and one of the infrared receiver. Compared with the detection based on one of the infrared emitter and one of the infrared receiver in the prior art, the detection based on multiple of the infrared emitters and one of the infrared receiver is more accuracy and multifunctional.

Step 100: the information receiving element 210 of the interactive control module 200 receives a moving control instruction from a user and transmits it to the main control board 220 of the interactive module 200;

In the step S100, the moving control instruction includes instructions such as advance, retreat, left turn, and rotation.

Step 200: the main control hoard 220 sends a driving instruction according to the moving control instruction to the moving mechanism 300 and control it to move according to the moving control instruction. During the moving process of the moving mechanism 300, the posture control element 240 of the interactive control module 200 controls the shell 10 to turn or go straight ahead at correct angles.

When the user interacts with the smart interactive toy, the information receiving element 210 of the interactive control module 200 receives the moving control instruction from the user and sends it to the main control board 220 of the interactive control module 200. Then, the main control board 220 controls the moving mechanism 300 to move the shell 100. In order to ensure the angle and the posture stability during the moving process, the posture control element 240 in the interactive module 220 controls the smart interactive toy to turn or go straight in correct angles. When the moving mechanism 300 is moving, the main control board 220 controls the first signal sending unit 410 to emit a first sensing signal in the direction of the signal transmission. When the signal receiving unit 420 does not receive the first reflected signal, reflected after the first measuring information meets obstacles, in the predetermined time period, it indicates that the smart interactive toy is at an edge of the table top or encounters a deep pit, and it will fall down if it continues to moving forward. Therefore, a first electrical signal is sent to the interactive control module so that the interactive control module 220 drives the moving mechanism 300 to stop moving, turn, or retreat, thereby achieving that the user controls the smart interactive toy to avoid it from falling down the table or into a deep pit, which ensures that the toy can be interacted and is not easy to damage.

Referring to FIG. 10 , in accordance to another embodiment of the present invention, the method of using the smart interactive toys also includes the following steps:

Step 410: the information receiving element 210 receives the interactive learning instruction from the user and sent it to the main control board 220.

Wherein, the interactive learning instruction is an instruction for starting an interactive teaching function of the smart interactive toy, which is mainly for children.

Step 420: the main control board 220 controls the moving mechanism 300 according to the interactive learning instruction to move according to the presetting first mobile path, and control an information displaying element 230 in the interactive control module 200 according to the presetting first mobile path to play presetting interactive learning question, which correspond to the presetting first mobile path, and the information displaying element 230 plays the presetting interactive learning question in a manner of a voice or a display interface.

In Step 420, the presetting first mobile path includes actions such as advance, retreat, left turn and rotation. The preset interactive learning question is corresponding to the presetting first mobile path, for example, the presetting first mobile path of the action “advance” is corresponding to the presetting interactive learning question of “does I turn left?”. Both of the presetting first mobile path and the presetting interactive learning question are pre-input and stored in the memory of the main control board 220.

Wherein, the voice is played through the player 231, the displaying interface is used for playing the interactive learning question through the displaying component 232, for examples, performing information projection through the projection lamp 2321 and the spotlight board 2322, or setting a display device, which is used for displaying the interactive learning question and realizing an interface-type interactive learning and improving the enjoyment.

Step 430: the information receiving element 210 receives interactive answer from the user according to the interactive learning question, and sends the interactive answer to the main control board 220.

Step 440: the main control board 220 determines whether the interactive answers are correct. If the interactive answer is correct, it controls the information displaying element 230 plays the encouraging voice, if the interactive answers are wrong, it controls the information displaying element 230 plays the teaching voice, wherein the information displaying element 230 displays the encouraging voice and teaching voice in a voice or a display interface.

Specifically, in Step 440, when the user sends an interactive learning instructions “starting intelligent teaching”, if the main control board 220 controls the moving mechanism 300 to drive the shell to turn left, then controls the player 231 of the interactive control module 200 to play “did I turn left?”, if the children answers “no, you didn't”, the main control board 220 judges that the answer is wrong and plays the teaching voice, for example, “I turned left just now”, if the children answers “yes, you did”,then the main control board judges that the answer is right, and plays the encouraging voice, for example,“your answer is right, great.”

Further, after receiving the interactive learning instructions from the user, through controlling the moving mechanism 300 to move the first moving path and playing the interactive leaning question, the interactive and the basic knowledge teaching to the children are realized through the movement of the smart interactive toy and the questions from the smart interactive toy, which overcomes the deficiencies caused by the individual audio teaching mode in the prior art, such as boring teaching, not strong interactive and poor teaching effect.

The above are only better embodiments of the invention and are not used to limit the invention, and any modifications, equivalent replacements, and improvements made within the spirit and principles of the invention shall be included within the protection of the invention.
